60x85x8 NBR AO TC Rotary Shaft Seal Double Lip

Industrial Applications

Simmering 60x85x8 NBR AO TC is a double lip rotary shaft seal designed for dynamic sealing of 60 mm shafts in oil lubricated industrial systems. Within the Rotary Shaft Seals NBR TC Oil Seals Double Lip category, the 60x85x8 mm version represents a reinforced configuration compared to thinner 6 mm variants, offering increased stability under moderate mechanical loads.

This 60x85x8 NBR AO TC oil seal is commonly used in:

• industrial gearboxes

• electric motors

• hydraulic power units

• agricultural machinery

• drive assemblies and reducers

In installations exposed to dust and contamination, the additional AO dust lip improves external protection and helps extend overall sealing life.

Construction and Design

The Rotary Shaft Seal 60x85x8 NBR AO TC features a double lip TC construction. The primary sealing lip is spring loaded to maintain consistent radial contact pressure on the shaft surface, ensuring reliable oil retention. The secondary lip acts as a protective barrier against dirt, moisture and external particles.

The metal reinforced outer case guarantees a secure press fit in a housing with 85 mm bore diameter. The NBR nitrile rubber compound provides dependable resistance to mineral oils, lubricating greases and standard hydraulic fluids.

With an 8 mm width, this design offers improved axial stability compared to thinner seals, making it suitable for applications requiring enhanced mechanical robustness.
